* valprint.c (type_print_base): If the type being printed is a
	struct containing undefined types, print "<undefine type>"
	as the type instead of crashing.
	* values.c (value_headof): Get the vtable pointer taking
	TYPE_VPTR_BASETYPE into account.
	* symtab.c, symtab.h, dbxread.c: Fix various whitespace splotches.
